Title: Innovations by Rudolf V Zavodov in Fibrous Sheet Material Production

Introduction

Rudolf V Zavodov is a notable inventor based in Saint-Petersburg, Russia. He has made significant contributions to the field of fibrous sheet material production, holding 2 patents that showcase his innovative approach to this technology.

Latest Patents

Zavodov's latest patents include an "Apparatus for production of fibrous sheet material" and a "Method for production of fibrous sheet material and apparatus for." The apparatus comprises a slot nozzle with side walls normal to converging frontal walls. Its inlet opening connects with means for dispersing fibers in a gas stream, while the outlet opening communicates with a chamber. A flat screen is mounted under the chamber to form a fibrous layer, and a suction box is arranged underneath the flat screen. The design ensures that the side walls of the slot nozzle are parallel, and it includes means for removing part of the gas from the gas-fiber stream in the chamber.

The method involves dispersing fibers in a gas stream to create a gas-fiber stream, which is then supplied onto a flat screen. Gas is removed from the gas-fiber stream through the screen to form a fibrous layer. The process also includes removing part of the gas from the gas-fiber stream before it reaches the flat screen, while simultaneously damping transversal pulsations induced during movement. The fiber concentration is adjustable, ranging from 20 to 500 g/m³, depending on the specific fiber and its properties.
